Torque limiter free rotation DSS/SG/RF

Safety coupling to be mounted between the motor and gearbox with flange B5 spacer. Available in sliding (DF) and disengage versions (DSS/F/SG-PR-V). The location of the limiter between the motor and gearbox requires a smaller size of device with also reduces costs.

  • Safety joint made of steel, aluminum spacer completely machined;
  • Anti-corrosion treatment standard phosphate on the torque limiter;
  • Compact solution;
  • The device worked for IEC motors and gears;
  • Protection in both directions of rotation;
  • Disengaging instant to overcome the torque set;
  • Simple calibration system with H fee for an immediate calibration of the device.
  • The device is already configured and ready to use;
  • Possibility of friction rings with different performance in the case of model slip;
  • Free rotation backlash free balls model according to ATEX conformity;
  • Possibility of surface treatments for corrosion-specific needs.
  • Conveyor belts;
  • Packing machines;
  • Packaging machines;
  • Systems for handling and positioning.
  • Best simplicity and sensitivity to integrated solutions in reducing them;
  • Protect the gear motor from accidental collisions or impacts of the product limit;
  • Reduce downtime in the event of overload;
  • Absorb starting torque without disconnecting the transmission.
